If 𝑋 is the set of numbers three, four, nine, and eight and 𝑌 is the set five, zero, what is 𝑋 minus 𝑌?

We recall that when subtracting sets, 𝑋 minus 𝑌 means the elements of 𝑋 that are not elements of 𝑌. In this question, all four elements of 𝑋 — three, four, nine, and eight — are not elements of 𝑌.

This means that the correct answer is the set three, four, nine, and eight.
